1990 No Crank - ZR-1 Net Registry Forums

SAHall · 10-30-2019

I am experiencing a no start on my 1990 ZR-1 with 16,000 miles. The car has power, but the starter does not crank. I don’t think it’s the vats system or the clutch switch. When I turn the ignition to start and push the clutch pedal down the starter does not engage, but the gauge shows a small voltage drop when the clutch switch is activating.

The battery is new and I tried starting with a battery booster just in case it was a power issue. No change.

While it may not be related, the vacuum pump is also making an unusual grinding or clicking noise when the key is first engaged.

Any advice. Is it the starter? Hope not.
